An update: Isaac's hens are adjusting to being with Deacon, the blue Rock hens more so than the head hen, June. June is having the most difficult time accepting Deacon, but even Georgie who has never been with another rooster other than Isaac (and Deacon when he was much younger), has accepted his presence back with the group.
Neela, one of the blues, is extremely thin and has a cyst-like protrusion from her left nare that has closed most of it off, but it bleeds if you mess with it so I've left it alone. I'm dreading Deacon losing her because he's experienced the loss of three hens already, yet, I've given him a bunch of older hens so it's inevitable, I suppose. For a consolation prize, Little Tessa, Atlas's daughter out of big Ida, will be Deacon's girl when she's old enough; she's almost 14 weeks old. Deacon seems happy and Rita is getting along with Ike's hens better than she was at first. I still feel a big hole with Isaac gone; my DH commented on it just today.
